Coconut shell biochar application in liquid-solid microextraction of triazine herbicides from multi-media environmental samples

The potential of lignocellulosic biomass for magnetic solid phase extraction of naproxen from saliva samples

“…Currently, several studies showcase the utilization of biochars in SPE cartridges, MSPE, or solid phase microextraction (SPME) techniques to extract pollutants, such as triazine herbicides, 13 organophosphorus pesticides, 14,15 and anti-inflammatory drugs. 16 MSPE, based on the use of a magnetic sorbent, is a better alternative approach that can facilitate the separation of a powder material with an external magnet, eliminating filtration and centrifugation steps and thus providing the advantage of easy operation.…”
